Configuring MoFRR

Prerequisites for MoFRR

• Ensure IP Multicast is enabled. For more information on configuring IP Multicast, refer Cisco Nexus
• Ensure that you have disjoint ECMP paths towards the source.

Guidelines and Restrictions for MoFRR

• The MoFRR feature is disabled by default and must be enabled using the CLI.
• MoFRR feature is supported on Cisco Nexus 7000 Series Switches, F3/M3 line cards only.
• The Equal Cost Multipath Protocol (ECMP) feature is a requirement for the MoFRR feature to function.
• If ECMP is not configured, the two paths that are chosen from the ECMP paths are based on the RPF
• MoFRR works only for Sparse Multicast (SM) S, G, and Source Specific Multicast (SSM) routes.
• MoFRR is applicable to only IPv4 Multicast, not IPv6 Multicast.
• MoFRR does not support extranet routes.
• MoFRR works where the Reverse Path Forwarding (RPF) lookups are done in a single VRF.
• Both primary and secondary paths should exist in the same multicast topology.
• MoFRR is supported on images supporting IPv4 MFIB only.
• We recommend that you enable MoFRR feature on the last hop router.
